ERR_CMD_UNKNOWN

[oleid]

Hey,

I'm trying to connect to a device via XCP/TCP and get a crash due to an unknown command:

$ python xcphello.py -c conf_eth.toml  -d -l DEBUG
DEBUG:pyxcp.transport.Base:CONNECT

I'm new to the XCP world, so any pointers would be highly appreciated.

Thanks a lot!

Just comment out
# identifier = x.identifier(0x01)
and three lines below
# print(f"ID: '{identifier}'")

While optional, XCP slaves usually ship with a GET_ID implementation -- this is not the case here.
You may also try the --daq-info option.
python xcphello.py -c conf_eth.toml -d -l DEBUG --daq-info
If there is a ERR_ACCESS_LOCKED error, just ask.
